Biochemical studies of some non conventional sources of protein. Part 4. The proteins of mango waste stone kernels

Abstract

The gross chemical composition, protein content and amino acid composition of mango stone kernels of four Egyptian varieties (Ewsi, Hendi, Fonso and Timour) were investigated. Carbohydrates are the main components of the seed. The protein content varies between 5.0 and 7.2% and the ether extract ranged from 10.8% to 13.6%. High glutamic acid, aspartic acid and leucine content and low concentration of sulfur-containing amino acids are characteristic for the proteins of mango kernels. Lysine level is also low, the concentration of other essential amino acids is acceptable. Sulfur-containing amino acids are the first limiting ones followed by lysine and threonine.

“…In the processing industry, 35-60% of this fruit is discarded as waste (Ram, 1973; Beerh et al, 1976), mainly in the form of peel, stones, and pulp. The seed kernel is a source of fat (11-13%) and carbohydrate (65-67%) (Lasztity et al, 1988). The peel and fibrous pulp containing many flavoring substances and rich in sugars can be used for preparation of wine and vinegar after fermentation (Beerh et al, 1976).…”
